Asplenium trichomanes

Asplenium trichomanes



About this cultivar:

Asplenium trichomanes is a small fern occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.

The specific epithet trichomanes refers to a Greek word for “fern” and it is commonly known as maidenhair spleenwort

It grows in tufts from a short rhizome and grows everywhere, and I mean everywhere. It grows in rocky habitats such as cliffs, scree slopes, walls, and mine waste, the type of rock used as a substrate depending on the subspecies. It grows from sea-level up to 3000 metres in North America while in the British Isles it reaches 870 metres. Hardy to minus -20 degrees you’ll see this on some freezing South American mountain rock face as often as you will in some bathroom (as a houseplant of course….).

It has the RHS award of Garden Merit.

    About this genus:

    Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the Spleenwort family (Aspleniaceae) but I’m sure DNA results will change all that soon.

    The most common vernacular name is spleenworts, applied to the more "typical" species. Asplenium nidus and several similar species are called bird's-nest ferns, the Camptosorus group is known as walking ferns, and distinct names are applied to some other particularly well-known species.

    Many groups of species have been separated from Asplenium as segregate genera but these species can form hybrids with other Asplenium species and because of this are usually included in a more broadly defined Asplenium.

    Both the scientific name and the common name "spleenwort" are derived from an old belief, based on the doctrine of signatures, that the fern was useful for ailments of the spleen, due to the spleen-shaped sori on the backs of the fronds. "-wort" is an ancient English term that simply means "plant" (like in German ‘wurz’). The genus name is Latin asplenum for spleenwort, from Greek asplēnon, irregular from splēn meaning….spleen.

    As you’d expect with over 700 species it is hard to generalise but some of them are great ornamental plants. Ummm, like most ferns, good in full shade to part shade. Not to dry please. I love ferns so I think just grow them where you can – verdant!
